Field measurement of harmonic pollution levels:
Controlling harmonic pollution is basic to avoid faults in regulation systems, overloads at capacitor banks, resonances with dangerous overvoltages and overcurrents, anarchic behavior of protections...

Measurement of electrical disturbances (gaps, micro-blackouts, impulsive voltages...)
All these electrical disturbances have a random behavior and their duration is very short. However, their effects are very harmful. S.T.&M. raises solutions attacking to the origin of the problem or immunizing the affected systems.

Habitual tasks are:

- Recording loads or other parameters.
- Verification of electricity meters or of other measurement equipment.
- Soil resistivity measurement, previous to the grounding system design.
- System topology review after some years of a maybe not very controlled growth.
- High voltage wires testing services.
- Adaptation of measuring systems to regulation.
- Generation of documentation according to regulation.
- Consultancy services (regulation, technical aspects...)
